Braving the Extremes: Tips for Keeping Your Aircon’s Peak Performance

Aircon Deep Clean

Singapore’s tropical climate is known for its sweltering heat and sudden downpours.

These unique weather patterns, while offering us the allure of sun-kissed days or rain-soaked times, also present distinct challenges for our home comforts, particularly for our trusty air conditioning units.

For Singaporeans, the aircon isn’t just about luxury; it’s an escape– a haven from the relentless heat or the bulwark against stifling humidity.

But how can we ensure that this cooling companion remains at its prime whether rain or shine?

Whether you’re a seasoned local familiar with the mercurial weather or an expat still adjusting to the tropical dance of sun and rain, optimising your aircon for Singapore’s climate extremes is crucial.

So, join us as we explore how to master the balance and get the best out of our air conditioning units all year round.

Optimise Cooling During Singapore’s Scorching Heat

For context, you can do these actionable steps during the warm season but we suggest you do it during Singapore’s hottest months—April, May, and June.

1. Ensure Regular Cleaning and Maintenance

The AC’s filters, coils, and fins require regular maintenance for the unit to function effectively. This is because dust, dirt, and grime can accumulate during peak usage. Dirt-clogged filters can block normal airflow and significantly reduce a system’s efficiency.

So, make sure you clean or replace your filters every month!

2. Opt for a Smart Thermostat

A smart thermostat can automatically adjust temperatures based on usage patterns and ambient conditions. They can also track your energy usage and reduce your energy consumption.

These easy-to-install devices can help maintain optimal temperature in your home, thus avoiding unnecessary cooling and excessive energy consumption.

3. Seal Your Living Space

Ensure that your home is sealed properly. Make sure to check for gaps around windows, doors, and other openings. If you do find some gaps, use weather strip seals or caulk to prevent cool air from escaping.

This makes your aircon work less to maintain your desired temperature.

4. Use Fans

Use fans to circulate the air produced by your aircon. This ensures even distribution of cooling. By doing this, you can set your thermostat a degree or two higher without compromising your comfort.

5. Manage Sunlight

Sunlight streaming through your windows can quickly transform your living space into a greenhouse, making your air conditioner work overtime to combat the increased heat.

So, use your blinds or curtains to block out sunlight during the hottest parts of the day. This will lessen the work your aircon needs to do to cool your space.

Maintaining Your Aircon During Singapore’s Rainy Season

While you can expect rain throughout the year, Singapore experiences a lot of rain from September to February. So, make sure you do these actionable suggestions to preserve your aircon’s efficiency during the wet season.

1. Regularly Check and Clean the Outdoor Unit

During the rainy season, debris like leaves, twigs, and trash can get lodged inside the outdoor unit. This can cause obstructions and the eventual breakdown of your unit.

So, regularly check your unit and keep it and its surrounding areas clean.

2. Protect the outdoor unit

Consider installing a protective cover or a shelter for your outdoor unit.

This isn’t to prevent rainwater. In fact, aircon units are designed to handle that. Rather, this is to prevent potential damage from falling objects or debris carried by strong winds.

3. Inspect for Mould and Mildew

While Singapore has relatively humid weather, this humidity can skyrocket around December. Unfortunately, high humidity can lead to the growth of mould and mildew.

These not only reduce the efficiency of your AC but can also lead to health problems.

So, regularly inspect your unit’s components for signs of growth and if you’ve detected any, have them cleaned immediately.

4. Ensure Proper Drainage

Rainwater can lead to pooling around the outdoor unit. If left unchecked, this can lead to problems like rusting or even electrical malfunctions. It can also be a breeding ground for mould and mildew.

Make sure there’s a proper drainage system in place to channel water away from your unit.

5. Schedule Regular Professional Check-ups

During the wet season, it’s beneficial to have your AC checked by professionals to detect any potential issues early. They can provide insights into component health, refrigerant levels, and potential mould problems.

6. Utilise Dry Mode

Many modern air conditioners in Singapore come with a “dry mode” function. This is particularly useful during the rainy season, as it reduces humidity inside the home without making it too cold.

Final Thoughts

Singapore’s unique climate demands a two-pronged approach to air conditioning maintenance.

By being proactive and adhering to the above guidelines, you can enjoy optimal cooling during the scorching heat and maintain efficient and healthy AC systems even during the wettest months.

With a well-maintained air conditioner, you can ensure that you’ll enjoy the comfort that it brings regardless of the weather.
